.l ated according to the invention in theinterior of; sections or cells. by means of dis'tributing structures in a direction in which the cooling; air' will at. least. along a short path find passage areas that are at? least twice aslarge as the ,e'ntranceor exit areas of the sections'orj cells. Thereby the: smallest velocities ot the cooling air-current are obtained.

within the;mostefiectivecooling zone. jPret erablythe Qdistributi n g structures in the sections-are arranged a substantially diagonal manneia;

matter of the present invention are. illustrated on. the accompanying drawings, in which:

The right hand end of Fig. 1 is a vertical longitudinal section on the line II of Fig.

2, and the lefthand end is a sideview of a re-cooler having a lateral entrance for :the
